PITI stands for Principal, Interest, Taxes, and Insurance — the four components of a real monthly mortgage payment. Most people only think about principal and interest, then get surprised at closing. Here’s the full number, broken down.
The one-sentence definition
PITI is the true monthly cost of owning a mortgaged home: the loan paydown (principal), the lender’s charge (interest), property tax, and homeowners insurance — usually paid as one combined monthly amount.
The four parts
- Principal — pays down what you borrowed. Small early in the loan, grows every month.
- Interest — the lender’s charge on the outstanding balance. Large early, shrinks as the balance falls.
- Taxes — county/municipal property tax, usually collected monthly into escrow and paid on your behalf.
- Insurance — homeowners (hazard) insurance, also typically escrowed.
Add PMI (if down payment < 20%) and HOA dues where applicable, and you have the full housing payment lenders actually use. Build the exact figure with the mortgage payment calculator.
Why PITI matters more than “P&I”
Lenders qualify you on the full PITI (plus HOA), not just principal and interest. A $400,000 home might show a $2,000 P&I payment but a $2,750 PITI once taxes and insurance are added — that $750 is the difference between qualifying and not. It’s also why two identical homes in different states have very different payments: property tax varies enormously (see the property tax calculator).
A worked example
$400,000 home, $320,000 loan, 6.5%, 30-year:
| Component | Monthly |
|---|---|
| Principal & interest | ~$2,022 |
| Property tax (1% of value) | ~$333 |
| Homeowners insurance | ~$150 |
| PITI total | ~$2,505 |
Add PMI (~$150 if under 20% down) or HOA and it climbs further.
Escrow: how PITI is usually collected
Most lenders bundle T and I into your monthly payment and hold them in an escrow account, then pay the big tax and insurance bills for you. This spreads lumpy annual bills into even monthly amounts and prevents a missed tax payment — but the lender controls that cash. Escrow is usually required when your down payment is under 20%.
What PITI does NOT include
- Maintenance (budget 1–2% of home value/year)
- Utilities
- One-time closing costs (use the closing cost calculator)
- Major capital repairs (roof, HVAC)
Qualifying for PITI is not the same as comfortably affording the home — see the full picture in the affordability calculator.
Frequently asked questions
Is PMI part of PITI? Technically PITI is four parts, but lenders add PMI and HOA to get the total housing payment they qualify you on. Always think in the full number.
Why did my PITI change after a year? Escrow adjusts. Property tax reassessments and rising insurance premiums change the T and I portions, so your monthly payment can rise even on a fixed-rate loan.
Can I pay taxes and insurance myself instead of escrow? Sometimes, with 20%+ equity and lender approval. You gain cash-flow control but take on the discipline of saving for big annual bills.
Does PITI go down over time? The P&I part stays fixed on a fixed-rate loan (the mix shifts toward principal). Taxes and insurance usually drift up, so total PITI often rises slowly.
How do I lower PITI? Bigger down payment (less principal, no PMI), shop insurance, appeal property tax, or buy in a lower-tax area. Model each in the mortgage calculator.
Bottom line
PITI is the number that actually leaves your account every month — plan around it, not the smaller “P&I” figure lenders advertise. Get yours exactly with the mortgage payment calculator.
